To-all whom 'it may concern:- 1

Be it known that'I, WILLIAM R. Pn'rzn, a citizen of the United States, and a' resident of Brooklyn, in the. county of Kings and State of New York, have invented certain new and useful Improvements in Spri -Repairers, of which the following is a spec' cation.

This invention relates to aV device for repairin semi-elliptic vehicle springs, and particular y. the springs of motor-cars and similar motor vehicles, and the main object of the inventionis to provide a device which can be readily applied to such a spring to reinforce the saine and permit the continued use of 15 such car or vehicle should a springl bei. frack;A

` e engt tured or broken at any point in t thereof.

It frequently happens that one of the semielli )tic springs of such a motor-car or vehiat aconsiderable distance from any point cle ecomes broken while the car is in use and where it is possible to -niake permanent repairs, and the chief purpose of such a device as that described herein .is to make a temporary repair which will permit continued use of the car Without removing'the damaged or broken spring and substituting a new one. Such a device in order to be of practical value must be capable of repairing any break that is likely to occur in such a semi-elliptic spring. These springs usually consist of a p ura it f ofv leaves of different lengths 'superimposer one u on the other, and a fracture or breakage o one or 'more of such leaves may take place at any point in the length of the spring. A device adapted to repair all breaks that may occur should therefore be so constructed that it may be applied to the spi-'ing at aiily point inthe length of the spring' 4o and secure i rnily thcreto'adjacent to the breakin' such a manner as to serve at least temporarily either as a means for strengthening portions ofthe spring adjacent to a fracture .or break, or as a substitute for a por- '45 tion of the spring completely broken off.

Such a device should be so' constructed as to permit the usual p lay of the different parts of the spring as it is put under tension or released, vand it should also be so formed as to 5o oppose a very reat resistance to the forces tending to brea it when the 'car containing the spring to which it is applied is in use. As such adevice may frequently have to be used to repair a break at :innear the end of the spring as .well as air-or nearthecenter all the igu thereof, the preferred construction is that in" which the device is so formed as to be capable of connection to a" vehicle by substantially the same means ordinarily employed to connect the carriage and one end of the spring.

In the drawings accompanying this speciication and forming part of the present application, Figure 1 isa side elevation of a semi-elliptic vehicle s ring having my device for repairing a brea iii the same applied thereto.

, es' Fig. 2 is an enlarged side elevation of the main portion or tie-piece of the s ring repairingy device. Fi I3 is a plan o the same. Fig. 4 is a si( e elevation of a twopart clip for securing the tie-piece to tle spring. Fig. 5 is an end elevation of one part of said clip. Fig. 6 is a transverse section of the tie-piece shown in Figs. 2 and 3.

Similar characters designateclike parts in res of the drawing.

Referrmgfrst to Fig. 1, 2 indicates a semielliptic vehicle spring of well-known construction usually employed as a means forsupporting the body of a motor-car or similar vehicle, the spring consisting of a sexies of superimposed leaves of different lengths held together in the usual manner b clips.

Ina`

spring of this type the upper eaf 4 is 'ordinarily bent over at its ends to form eyes by means of which the spring is connected to thel body of the vehicle. One of these e es is shown at `5. The other, in the view s own in Fig. 1, is not resent, it being assumed that the eye at tie right-hand end of the spring has been broken off. This is one of t e various points at which a break in the spring may occur. The main element ofthe means I employ for repairing a break in such a'vehicle vspring is a tie-piece considerably shorter than the spring itself and-adapted to be applied to 'the sprinfr in such a manner as to permit free lay of the spring as it is tensioned andre eased. For this reason the tie-piece is preferably arched, its curvature" 100 Thus when when inits operative osition being the reverse of that of the spring itself.

in place saidA tie-piece forms au arch which is y clear of the spring exce t at two points substantially at the ends o the tie-piece, and all that portion of the spring between such points is free to move substantially as in the case of a perfect spring. lhe tie-piece em- Y plo ed by me is itself a spring and an exceed- .-ing y strong one, for the reason that when in place its curvature is the opposite of ,that 'of .adjacent to a case oa break at or near the center of the- 50A of the vehicle.

the spring. The tie-piece which I prefer to em loy is indicated at 6. Near lone or 'botr-of its ends it is so constructed las to permit it to be firmly secured to the spring 2 in a i'xed position lengthwiseof saidspring.

f Preferably means willbe provided for fastenoints ing -itto the sprin at aPluralit-yof h ,re Il t a 'i in the spring.

o s iring, as indicated.,4 for example by the i otted lines in Fig. 1,v the tie-piece will be se cured to the springby means located at opposite sides.. off-the break; whereas, when it is fastened-to thesp'ring' in such position as to repair a break at lor 'near the end of .the spring, as indicated for example in full lines in Fig. 1, the two points of connection to the spring may b'e at the same 'side of the break in thev spring. At 'or near one ci' bothof its ends-the tie-piece 6 should have a stop or stops, such as the walls 7 These serve to locate endwise of the spring the means :for

fastening theme-piece to the spring, which means will ordinarily be clips adapted to 2;; straddle both the spring and the tie-piece and firmly bind them together.A Anysuitable clip ma be employed for thisA pur ose, though prefer-to use a type which w l be hereinafter more fully described.

At or near one or both ends thereof' the tievpiece G-wiil preferablybe of two'diiferent widths.. 'The largerdiniension inthis case is represented b5 the width of the main ortio'n and ends of the tie-piece. The sma ler dimansion is formed in this case by rectangular recesses in the edgkes of the tie-piece near the ends thereof. T ese recesses are indicated at 8. The provision of a tie-piece of different widths at its .ends permits the connection of y-40 said tie-piece to springs of diierentjvidths found on different types of motor-cars.

A tie-piece constructed as described up to this ointis capable of repairing most of the brea s that occur in semieelliptic velicie s rings, but there are other breaks, to wit,

-t ose occurring at or near the e ,e 5 of the' spring, which cannot be repaire unless the tie-piece is so formed as to be capable of cori'- nection at one or both of its ends to the body In order that the tiefpiece may be so connected` I have shown the tiepiece as so constructed that it may be connected to the body of such a vehicle substantially at the point that the eye 5 of the spring is ordinarily so connected. Moreover, the

s eciiic features of the connection will preferpossib e like those of the of th'e spring, 1n or er that the same a l? be as much as en I means may be employed for making connections between the vehicle body and the end of the tie-piece that is ordinarily employed for making a connection between thel vehicle body and the eye 5.' For this reasorr said Itie-piece at one or'both of its ends will referably bel of the same width as the end o the single two-part clip lleaf 4 adjacent to the'eye 5, and will have l, I

transverse ournal opening,- sucli as 9, at'oiie orvboth of i-ts'ends, of the saine diameter as.' the opening 10 in the eye 5, in order that thel i same connecting device may be used in the opening 9 that is ordinarily used in. the lopen#- ing 10 passing through the eye at the end' of the upper leaf of the spring.

The tieiece will generally be secured 75 the spring y devices ocated at or near opposite ends of the tie-piece. Two clips 11 are yshown in Fig. 1 for this purpose, these clips havingtwn posts 12 and a 'cross-piece 13,

which may be held in any adjusted position by stop-nutsl-l. Inl Figs. 4 and 5 Ihave il ustrated in'detail a t e 'of cli which may be applied to the tie-piece at et er the wide' or the narrow portion thereof, according as the.

spring2 is narrow orwide. The clip shown is Ysubstantially oi the ordinar type except that lar but smaller saddle portion 16 which h longitudinal guide-grooves 17 fitting thei'nb ner walls of he main saddle portion 15.' When the clipvis intended to t the wide portion of the tie-piece for application to a wide spring, this a moved and the main portion. of the clip is 'used in the ordinary manner. When, ho'wever, the tieiece is to be applied to a narrow s ring t Ae auxiliary sa 1 le-piece 16 is place inposition as shown in Fig. 4, and the two-part clip is placed over the tie-piece at the narrow part of the tie-piece adjacent to the recesses V8. B the use of such a clip a may be employed for either width of spring, and it will be unnec essary to provide two sets of clips of different sizes to fit sprin of different widths.

Surplus meta may be dispensed with and the weiglht-of'the tieiece reduced by lo'nv said tie-piece to said spring at one side of a .120 airing semi-elliptic ver..

break in the spring.
